Design Note
40V Input, 3.5A Silent Switcher ВµModule Regulator for Automotive
and Industrial Applications
Zhongming Ye
Introduction
The LTMВ®8003 is a wide input and output range stepdown ВµModuleВ® regulator featuring the Silent SwitcherВ®
architecture. Inputs from 3.4V to 40V can produce outputs
from 0.97V to 18V, eliminating the need for intermediate
regulation from batteries or industrial supplies. The pinout
is specifically designed to be FMEA compliant, so the output
stays at or below the regulation voltage during adjacent
pin shorts, single pin shorts to ground or pins left floating.
Redundant pins enhance electrical connections in the event
a solder joint weakens or opens due to vibration, aging or
wide temperature variations, such as in automotive and
transportation applications.
A complete solution fits a compact space not much larger
than the 6.25mm Г— 9mm footprint of the LTM8003,
including the input and output capacitors. The quiescent
current of typical 25ВµA, and wide temperature operation from
вЂ“40В°C to 150В°C (H-Grade) make it ideal for applications in
automotive, transportation and industrial, where space is
tight, the operational environment is harsh, and low quiescent …
